I think it is our call and duty to go at least at our nearest cemetery to free a soul from Purgatory with the provisions mentioned in the link for a plenary indulgence, they are not hard to do at all. It will be our greatest act of mercy on that day and will not be left unrewarded.

We never know if we may end up in Purgatory and wish a good soul would do the same for us, with at least a little prayer.
